So, i just bought a Laptop like 5months ago great specs and it performing well in work/light gaming.

after sometime, I've facing an issue that my computer unable to detect my Graphic Card (Nvdia), it start up/ runs normally just my graphic card cant be detected it run on Intel ® UHD Graphics only. So i had contacted the after sales service to fixed it. They had tried everything, cleaning / reinstall my graphic drivers, reformatting my PC (everything u could imagine) but the problems still came back after weeks.

Due to MCO, I'm not allowed to cross stat (which the shop/service central located in KL Damansara)so i had to figure a way, i switched my laptop running in NVidia Graphic Cards ONLY (in BIOS) instead of xHybrid( (which is Intel graphics and Nvdia). It works perfectly but i get backscreen after sometimes, which i have to force restart my PC for several times to get it works normally 

can anyone give me a hand with this? its kind of frustrating, had to WFH
